Patent CA-2045651-C (CA)
Inventor: SPAIN PATRICK LEON
IPC: B44F9/02
Filed: 1990-10-17
Granted: 1997-03-18
Abstract: A process for making plastic siding panels, such as outdoor weatherable vinyl panels with an embossed wood grain pattern, comprises extruding a vinyl sheet, and overlaying on the extruded sheet a flexible carrier sheet having coated thereon (a) matte release layer bonded to the carrier sheet, and (b) decorative coating on the matte release layer facing toward the extruded plastic sheet.  An embossing roll applies pressure at elevated temperatures to transfer the decorative coating from the matte release layer and bond it to the extruded sheet, while the embossing roll embosses a three-dimensional impression pattern in the laminate transferred to the extruded sheet.  The carrier sheet and its matte release layer are then released from the laminate transferred to the vinyl sheet.  The matte release layer transfers a low 75° gloss level, preferably in the range of 8 to 12 gloss units, while enabling free release of the carrier from the embossed low gloss surface at elevated temperatures. In one embodiment, a multi-layer wood grain printed acrylic/polyvinylidene fluoride blended decorative coating is simultaneously transferred to a vinyl extrusion and embossed with a three dimensional wood grain texture.  A color coat behind wood grain print coats contains pigment at a level that protects the vinyl substrate from UV deterioration.  The matte release layer contains a suspended wax which enhances forming the low gloss surface while improving release of the matte release layer from the transferred laminate.  A silicone resin in the matte release coat combines with the wax to further enhance release properties.

Title: Liquid infusion device
Inventor: TSUJIKAWA HAJIME
IPC: A61M5/152
Filed: 1991-07-03
Granted: 1996-08-06
Abstract: A liquid infusion device comprising a bladder assembly, an approximately tubular housing, and a liquid-drug-dispensing portion.  The bladder assembly comprises a rod-like inner shaft, a tubular outer shaft slidably encasing the inner shaft, an inner shaft supporter, and a bladder made of elastic material and placed outside two shafts. The housing contains the bladder assembly and has an inlet/outlet portion at an end of the housing. The inner shaft supporter has at least one port for liquid drug communicating with the inlet/outlet portion. An amount of liquid drug remaining in the bladder can be greatly reduced, since a clearance between the inner shaft and outer shaft can be made very small.

Abstract: A variable capacity type slant plate compressor including a crank chamber a suction chamber  and a discharge chamber is disclosed. The crank chamber is linked by a first communication path to the suction chamber, and is linked by a second communi-cation path to the discharge chamber.  A first valve control mechanism  is disposed within the first communication path. A second valve control mechanism is disposed within the second communication path.  The first valve control mechanism controls the opening and closing of the first communication path so that the suction chamber pressure is maintained at a predetermined constant value.  The second communication path is compulsorily opened by operation of the second valve control mechanism in response to an external signal so zas to compulsorily minimize the capacity of the compressor.  A throttling device is disposed within the second communication path between the discharge chamber and the second valve control mechanism so that thecapacity of the compressor is compulsorily quickly minimized without damage of the internal component parts of the compressor.

Title: Switching voltage regulator with protective device against thermal breakdown
Inventor: OHSHIMA YOSHINOBU
IPC: H03K17/082
Filed: 1992-03-12
Granted: 1997-04-15
Abstract: A  switching-type  voltage regulator of this invention comprises  a voltage  control  section  for   generating   a stabilized  voltage  by  controlling a voltage supply period from input side to output side, and a protective device. The protective device  monitors  the temperature  of  a  certain component  part or  parts  of  the voltage  control  section and convert the temperature into a voltage  to compare  with the  reference  voltage  generated  by a  reference  voltage source, and brings the output of the voltage control section to a halt  in accordance with  the result of comparison. The output of the voltage  control section is  brought to a halt regardless of the  presence  of output abnormalcy  when  the temperature  of   the  component  part  or  parts  monitored exceeds a certain level.  As  the monitoring  means,  it  is preferable  to  utilize  the  electrical  characteristic  of semiconductor  p-n  junction  changing with temperature, and a  semiconductor  diode  is  more preferable.  A  preferable halting  means  is  a  2-input  AND  circuit  where a signal representing the result of the  comparing means are inputted into  one  of the input terminals,  and  a switching control signal  to  the  other  to  control  a  switching   element.          Preferably,  a  latching  means  is  installed  between  the comparing  means  and  halting  means  to  maintain a halted condition.

Packaging containers (10)  of the present type also serve at the same time for the presentation of the pack content during the sale of the latter. For this purpose,  the packaging container (10)  is open on the upper side (20).        In order nevertheless to protect the pack content during transport and storage, there is arranged in the region of the open side (20) of the packaging container (10) a cover cap (21). This consists of a covering wall (22)  and  of  longitudinal  insertion  tabs  (23)  and transverse insertion tabs (24). The latter are fixed in a gap (25) between the pack content and the side walls (12 to 15). 2.2.    In the production of a packaging container (10) of the foregoing type, the procedure can appropriately be such that a blank for the cover cap (21) and a group of small packs (11) as the pack content are pushed into the packaging container  (10)  jointly by way of the open bottom side of the latter. At the same time, an automatic folding of the insertion tabs (23, 24) of the cover cap (21)  into the position appropriate to the pack takes place.

Title: Process for producing gypsum flake from flue gas desulfurization
Inventor: WELLIVER WILLIAM R
IPC: C01F11/46
Filed: 1992-09-18
Granted: 1999-06-29
Abstract: ABSTRACT           This invention relates to an improved process for producing gypsum calcium sulfate dihydrate flakes from powdered gypsum calcium sulfate dihydrate obtained from the desulfurization of flue gas by the wet limestone process.  The flakes have sufficient size and strength such that the gypsum calcium sulfate dihydrate can be handled and processed in conventional equipment commonly used by wallboard manufacturers and others in the construction industry.  The intermediate calcium sulfate dihydrate from the desulfurization process is dewatered to about 5 to 12% by weight and then compressed into a thin sheet under a compaction or compression load of 4 tons force to 15 tons force per linear inch of sheet width.  A linear speed of from 0.5 to 2.5 feet per second is maintained during compaction providing a compaction residence time of from about 0.2 to 1.2 seconds.  An elevated temperature is maintained during the compaction process to enhance the reformation of the crystal size and shape of the gypsum calcium sulfate dihydrate.     The combination of pressure and temperature on the moist gypsum calcium sulfate dihydrate alters the physical characteristics of the gypsum calcium sulfate dihydrate, thereby resulting a sheet which breaks into hard flakes on exit from the compaction zone.

Granted: 1998-07-07
Abstract: A DQPSK delay detection circuit is provided that can securely reproduce stable clock signal.  An absolute value circuit ABS calculates an absolute value of I signal. An absolute value circuit ABS calculates an absolute value of Q signal.  Subtraction circuit generates a P signal according to the difference between the absolute values of I signal and Q signal.  Zero-cross detection circuit detects zero-cross timing of the P signal to input it as a timing signal to the DPLL.  The zero-cross timing of the P signal can be detected even when the data pattern of I or Q signal makes it impossible to detect the zero-cross timing from I and Q signal.  Because the zero-cross timing of the P signal has a variation less than that of the zero-cross timing determined from I or Q signal, it is becomes possible to reproduce stable clock signals and in turn reliability of data demodulation can be improved.
